Abstract

L'invention porte sur un procédé et un serveur de communication pour faire correspondre une adresse à une capacité de service, dans lesquels un serveur détermine si un service demandé dans une requête de service, tel que par exemple dans un message invite SIP (protocole d'ouverture de session), peut être déclenché avec un premier identifiant d'utilisateur. Le serveur détermine en outre un identifiant d'utilisateur de remplacement lorsqu'il est déterminé que le service ne peut pas être déclenché avec le premier identifiant d'utilisateur, remplace le premier identifiant d'utilisateur par l'identifiant d'utilisateur de remplacement dans la requête de service, de telle sorte que le service demandé peut être établi avec succès.
